This is a short, application of equations of motion. The problem statement and the approach to solution is discussed. A police inspector in a jeep is chasing a pickpocket in a straight line. The jeep has a maximum uniform speed v. the pickpocket rides on a motor cycle of a waiting friend when the jeep is at a distance d away, and motor cycle starts with constant acceleration a. What should be the speed of police to caught pickpocket?

Imagine that the pickpocket is caught at a time t after motor cycle starts. The distance travelled by the motor cycle during this interval is

Step1: Selection of material The structural designers should know well about the characteristics of the materials available in market. In the market so many materials are available. From those, first you have to select correct one. It means, the selected material should have the following properties, •Good material properties such as toughness, yield properties…etc. •Cost •Availability •Easiness for handling •Weight to strength ratio. •Good assembling property such as weldability…etc. For the purpose, the materials can be divided as ductile, plastic and rigid material. Ductile material means, it will regains its original shape after removal load. But the deformation will be permanent for plastic material. And rigid material will not deform for the applied load. But actually, these materials are not exists. Which means, in real, no material is absolutely elastic, plastic and rigid. But we will assign the names if the deformations, and behaviour are within certain limits. Structural members are…
